Laser-plasma accelerators have proven to be a compact source of ultra-relativistic electron beams, generating GeV beam energies over only a few centimeters. However, the laser-plasma interaction, and thus the phase-space of the generated electron beam, is very sensitive to the initial properties of the driver laser. Here, we present the impact of laser pulse properties, specifically the higher order phases of the laser pulse, on the electron beam properties. By tuning the magnitude of the second (GDD) and third-order (TOD) dispersion of our 200 TW laser pulse, we can optimize the laser parameters for enhanced electron beam quality.
